How to work sim unlock on vivo using "oem.img"?
- OEM.IMG plays a crucial role in unlocking the bootloader on Android devices and is also essential for flashing devices. Before initiating the flashing process, the first partition written is OEM.IMG on your Android device. Neglecting this important file can lead to various issues with your Android smartphone.
- I have used the OEM file to rewrite certain addresses on Vivo devices, enabling the unlocking of the SIM network. Attempting to directly write the address is typically not feasible due to security protections. To unlock the SIM network service on Vivo mobiles using the SP Flash Tool, you need to rewrite the "Preloader" and "CUST" partitions. This action reconfigures the settings on your Vivo device, eliminating the SIM lock and allowing you to use your mobile without any complications.
